Water and Wastewater

The water services industry is the fourth-most energy intensive sector in the EU, and is responsible for considerable contributions to climate change via CO2 emissions.

Trinity has reduced its water consumption by 40% since 2010. On this webpage you can find out how to reduce your water use and wastewater generation. Trinity has committed to these objectives as part of our Green-Campus Programme:
